Description
Es ist bekannt, Hochdruckschmieröle herzustellen, indem man Schmierölen aromatische Nitroverbindungen zusammen mit Schwefel zugibt. Ferner ist bekannt, als Zusätze für Schmieröle Gemische aus aromatischen Nitroverbindungen neben Umsetzungsprodukten von Olefinen mit Schwefel oder auch solche aromatische Nitroverbindungen zu verwenden, die gleichzeitig ein oder mehrere zweiwertige Schwefelatome am aromatischen Rest gebunden enthalten.It is known to produce high pressure lubricating oils by adding aromatic nitro compounds to lubricating oils added together with sulfur. It is also known to use mixtures of aromatic oils as additives for lubricating oils Nitro compounds in addition to reaction products of olefins with sulfur or also those aromatic To use nitro compounds which simultaneously have one or more divalent sulfur atoms on the aromatic Rest bound included.
Es wurde nun gefunden, daß man besonders gute Hochdruckschmieröle erhält, wenn man Schmierölen auf Kohlenwasserstoffbasis oder Nichtkohlenwasserstoffbasis ein bei Temperaturen oberhalb 130°, zweckmäßig zwischen 150 und 200°, gewonnenes Umsetzungsprodukt aus 1, 2, 4-Trichlor-5-nitrobenzol, Styrol und elementarem Schwefel zugibt. Diese Umsetzungsprodukte enthalten den Schwefel nicht am aromatischen Kern gebunden, sondern an die olefinische Doppelbindung angelagert. Die zugesetzten Mengen des genannten Umsetzungsproduktes sollen 0,1 bis 10 Gewichtsprozent betragen; im allgemeinen sind Mengen zwischen 0,5 und 5 Gewichtsprozent ausreichend. It has now been found that particularly good high-pressure lubricating oils are obtained when lubricating oils are used Hydrocarbon-based or non-hydrocarbon-based one at temperatures above 130 °, expedient between 150 and 200 °, obtained reaction product from 1, 2, 4-trichloro-5-nitrobenzene, styrene and elemental Admits sulfur. These reaction products do not contain the sulfur bound to the aromatic nucleus, but attached to the olefinic double bond. The added amounts of the reaction product mentioned should be 0.1 to 10 percent by weight; in general, amounts between 0.5 and 5 percent by weight are sufficient.
Als vorteilhaft hat sich herausgestellt, bei der Umsetzung von 1,2, 4-Trichlor-5-nitrobenzol, Styrol und elementarem Schwefel molare Mengen anzuwenden, da hierbei ein bei normaler Temperatur flüssiges Reaktionsprodukt erhalten wird, das leicht in den zu verbessernden Schmierölen gelöst werden kann. Bei Anwendung anderer Mengenverhältnisse erhält man ein Gemisch aus flüssigen und festen Anteilen, das sich weniger gut in den Schmierölen löst, aus dem aber die festen Anteile verhältnismäßig leicht abgetrennt werden können.It has been found to be advantageous in the implementation of 1,2,4-trichloro-5-nitrobenzene, styrene and molar amounts of elemental sulfur to be used, since this gives a reaction product which is liquid at normal temperature and which can easily be improved in the Lubricating oils can be dissolved. If other proportions are used, a mixture of liquids is obtained and solid fractions, which dissolve less well in lubricating oils, but from which the solid fractions are proportionately can be easily separated.
Man legt in einem Rührkolben 100 Gewichtsteile Schwefel vor und gibt bei 160 bis 170° langsam eine feine pulvrige Aufschlämmung von 226 Gewichtsteilen 1,2,4-Trichlor-5-nitrobenzol zu. Nach 3 bis 4 Stunden bei 160 bis 170° erhält man ein bei Normaltemperaturen braun gefärbtes flüssiges Umsetzungsprodukt, das rückstandslos filtrierbar ist. Es enthält 19,5 Gewichtsprozent Schwefel, 2,4 Gewichtsprozent Stickstoff und 20,6 Gewichtsprozent Chlor. Gibt man 0,1 bis 10 Gewichtsprozent dieser Flüssigkeit zu Mineralölen oder zu Schmierölen mit polaren Gruppen, so erhält man z. B. bei 4°/0igem Zusatz die in der nachstehenden Tabelle im Vierkugelapparat ermittelten Ergebnisse.100 parts by weight of sulfur are placed in a stirred flask and a fine powdery suspension of 226 parts by weight of 1,2,4-trichloro-5-nitrobenzene is slowly added at 160 ° to 170 °. After 3 to 4 hours at 160 to 170 °, a liquid reaction product which is brown in color at normal temperatures and which can be filtered without leaving any residue is obtained. It contains 19.5 percent by weight sulfur, 2.4 percent by weight nitrogen and 20.6 percent by weight chlorine. If 0.1 to 10 percent by weight of this liquid is added to mineral oils or to lubricating oils with polar groups, z. B. at 4 ° / 0 sodium addition the results determined in the following table in the four-ball apparatus.
Aus den angeführten Zahlen ist ferner ersichtlich, daß das bei der Umsetzung der genannten drei Stoffe erhaltene Reaktionsprodukt bei der Zugabe zu Schmierölen eine bessere Wirkung zeigt als die Mischung der drei Komponenten (vgl. Versuch 5).It can also be seen from the figures quoted that this is obtained when the three substances mentioned are reacted Reaction product when added to lubricating oils shows a better effect than the mixture of the three components (see experiment 5).
Ferner ist ersichtlich, daß das beanspruchte Reaktionsprodukt auch dem bekannten Zusatz von Gemischen aus It can also be seen that the claimed reaction product also consists of the known addition of mixtures
